Model: FL57BLS02-36V-4000B-8P
-
FL57: This is the frame size. It indicates a NEMA 23 standard motor body (57mm square flange).
-
BLS: Likely stands for BrushLess Servo (or Stepper), confirming it’s a closed-loop stepper/servo hybrid motor.
-
02: Often indicates the stack length or motor version. A higher number usually means a longer motor and more torque.
-
36V: The rated voltage is 36V DC.
-
4000B: The “4000” very likely refers to the motor’s maximum speed of 4000 RPM under appropriate drive conditions. The “B” may be a revision code or denote a specific winding.
-
8P: This almost certainly means 8 Poles. A higher pole count in a brushless motor generally provides smoother low-speed operation and higher torque density.
Key Specifications :
-
Type: Hybrid Brushless DC (BLDC) Stepper/Servo Motor. It’s a closed-loop system, meaning it uses the encoder for precise position/speed feedback, correcting for missed steps.
-
Voltage: 36V DC (rated/nominal operating voltage).
-
Max Speed: 4000 RPM. This is a high speed for a stepper-type motor, made possible by its brushless design and proper driver.
-
Frame Size: NEMA 23 (57mm x 57mm mounting flange).
-
Encoder: Integrated. This is essential for the closed-loop operation. The resolution (e.g., 1000 CPR) isn’t specified in the model number but would be in the full datasheet.
-
Poles: 8.
Typical Applications:
This motor is designed for industrial automation and high-performance applications where reliability, speed, and precision are critical:
-
CNC Routers (small to medium)
-
3D Printers (high-end, professional)
-
Automated Guided Vehicles (AGVs)
-
Precision conveyor systems
-
Robotics
-
Pick-and-place machines
